It’s 3 a.m. and it would be nice to turn the TV and lights off without getting out of bed.

Knocki is a short, cylindrical device that attaches to any surface and transforms that surface into a touch interface that can control other devices. Users set Knocki to perform specific actions through a set number of taps. It uses non-acoustic sensor technology to detect gentle surface gestures that are even a short distance away, but Knocki also has the ability to filter out random vibrations. The device works anywhere there is Wi-Fi, and there is a companion Android and iOS app for it.

Each Knocki includes a mount featuring patent-pending SurfaceLink technology that ensures a solid connection to a surface for transmission of gesture signals. Knocki’s mount can be secured using the included 3M removable tape, or with screws that are also included. Knocki ships in December at future pricing of $129. But Kickstarter backers can get one for a pledge starting at $79 for early birds. Its makers are out to raise $35,000 by July 2.

As long as it’s compatible with every device one would want to be turned off without leaving the bed –- not necessarily a sure thing, at least initially — Knocki is a device that pretty much any consumer may find convenient. Its makers say they are constantly adding integration with new smart home platforms, devices and software, and have a goal of making Knocki more capable over time. The device is likely especially useful for those with mobility or vision impairments who can’t reach or visually locate a switch, button or smartphone.
